Question
In Java
All displayed prompts and results should be well formatted.
The assignment is based on the following Programming Exercise in the book: Programming Projects
Chapter 5 Defining Classes II Programming Exercises
Page 339
-Define a class named HotDogStand that has an instance variable for the hot dog stand's ID number and an instance variable for how many hot dogs the stand has sold that day.
-Create a constructor that allows a user of the class to initialize both values.
-Create a method called 'justSold' that increments by 1 the number of hot dogs the stand has sold. This method will be invoked each time the stand sells a hot dog
-Add a method that returns the number of hot dogs sold
-Add a static variable that tracks the total number of hotdogs sold by all hot dog stands and a static method that returns the value in this variable.
-Write a main method to test your class with at least 3 hot dog stands that sell a variety of hot dogs.
1. Hot Dog Stands
This assignment requires the following enhancements: There must be at least 2 java source code files:
· HotDogStandMainClass.java
Contains the main HotDogStandMainClass.
· HotDogStandClass.java Contains the HotDogStandClass.
Inventory Control
The hotdog stand class will have an inventory of hot dogs that the class must be able to track. The class must have methods to set, access, add to, and subtract sales from the inventory.
A hot dog stand class constructor must set the default initial inventory to 25 hotdogs.
Accounting
The hot dog class must keep track of the total hotdogs sold since its object instantiation.
Buy(int i) method
Instead of a sold method (as in the book) the hotdog class must have a buy method that has an parameter that indicates the number of dogs that wants to buy.
The hotdog class should be intelligent enough to sell only hotdogs that are in inventory.
If the buy is more than the inventory, the class should state the hotdogs in inventory and ask if the remaining (not 0) hotdogs in inventory is sufficient for the buyer.
If there is a buy when there are 0 hotdogs in invventory, the class should state that it is out of hotdogs to the buyer.
Develop a method called toString() for the hotdog stands class that displays a String object all the Hotdog stand object member values and states in a well formatted manner.
The main class must include driver code that tests all the logic paths of the hot stand class.
Do not use JPanel or interactive prompts, unit test the hot class by coding in test scenarios in the main program which will act as a driver.
You operate several hotdog stands. Define a class named HotDogStand that has an instance variable for the hot dog stand's ID number and an instance variable for how many hot dogs the stand has sold that day. Create a constructor that allows a user of the class to initialize both variables. Also create a method named justSold that increments by one the number of hot dogs the stand has sold. The idea is that this method will be invoked each time the stand sells a hot dog so the total can be tracked. Add another method that returns the number of hot dogs sold.
Add a static variable that tracks the total number of hot dogs sold by all the stands and a static method that returns the value in this variable.
